THE SANCTIONS` IMPACT

FINANCIAL: The bill bans all new public and private loans and investments in South Africa, except for reinvesting profits from South African enterprises, short-term credits and rescheduling of existing debt. The ban exempts loans and credits for education, housing or humanitarian projects and investments in firms owned by black South Africans. Remaining U.S. investments in South Africa last year totaled $31.3 billion. As of last March, U.S. banks held $329 million in deposits by South African banks and government agencies. Outstanding loans to South African agencies totaled $148 million last year. The bill would not require disinvestment, or withdrawal of existing loans or investments from South Africa.

IMPORTS: U.S. imports of South African iron, steel, arms, ammunition, military vehicles and farm products are prohibited immediately. A ban on imports of uranium, coal and textiles takes effect in 90 days. South Africa`s sugar import quotas are transferred to the Phillippines. Any direct or indirect imports from South Arican state-owned companies also are prohibited. The value of these imports totaled about $713 million in 1985. The bill makes permanent Reagan`s September 1985 ban on imports of Krugerrand gold coins, which accounted for $486 million in sales in 1984, the last full year of such trade.

EXPORTS: The measure bans exports of petroleum products, crude oil, munitions or nuclear technology or materials to South Africa. Also prohibited are exports of computers, software and services to the South African military, police or other agencies involved in administering the apartheid system of racial separation. The Commerce Department said computers topped the list of U.S. sales to South Africa last year, accounting for $80 million of the $1.21 billion in total exports. It was not known what portion of the $80 million went to South African government agencies covered by the sanctions. Petroleum, munitions and nuclear export figures were not available.

AIRLINES: The bill ends landing rights in the United States for South Africa Airways, which carreid 95,000 passengers to U.S. air terminals last year. The bill also bars U.S. air carriers from serving South Africa.
